Description

[Detailed Description of the Invention] The present invention relates to a crenelation for a passenger in a combat vehicle.

As a conventional embrasure, a crenel flange 2 is provided on a vehicle body 1 as shown in FIG.
A spherical surface 3 with a crenellation hole is provided in the periscope 5, and the barrel 4a of the gun 4 is inserted into the crenellation hole so that the gun 4 can be moved vertically and horizontally. At the same time, it is known to aim at the target based on the trajectory of the flash bullet fired from the gun 4.

With such a structure, as shown in FIGS. 2a and 2b, when the gun 4 is swung from side to side, the amount of change in the distance L of the periscope 5 increases, resulting in a problem that the shooting posture of the occupant deteriorates.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a crenelation that allows the occupant to always maintain a correct posture when swinging the gun from side to side.

Embodiments of the present invention will be described below with reference to FIG. 3 and subsequent figures. Note that the same members as those in the conventional example have the same reference numerals.

A barrel 4a of a gun 4 is provided on the side wall 1a of the vehicle body 1 via a crenelation flange 2 and a spherical surface 3 with crenellations.
An annular body 7 is provided on the upper wall 1b, and this annular body 7
A rotary seat 9 is rotatably provided through a shaft bearing 8, and a periscope 5 is provided on the rotary seat 9.

The rotary seat 9 and the gun 4 are connected via a link mechanism 10 so as to swing from side to side in synchronization.

The link mechanism 10 includes a first link rod 11 provided on the rotating seat 9 and a second link rod 12 supported on the upper wall 1b.
The third link rod 13 is pivotally connected to one end of the second link rod 12, and the other end of the second link rod 12 and the crenelated spherical surface 3 are connected by a third link rod 13.

Thus, when the gun 4 swings left and right, the periscope 5 swings (rotates) in the same direction via the link mechanism 10, so that the occupant can always obtain a good shooting posture.

In addition, a ball bush 14 is provided at the pivot connection portion of each link rod 11, 12, 13,
When the gun 4 is swung up and down, the movement is absorbed by the ball bush 14 and does not propagate to the rotary seat 9, so the gun 4 can be swung up and down.

The present invention is as described above, and when the gun 4 swings from side to side, the periscope 5 swings in the same direction, the distance between the gun 4 and the periscope 5 becomes approximately constant, and the occupant always maintains a correct posture while observing the periscope. 5 and the crenelated spherical surface 3 can be seen.

The periscope 5 is mounted on a rotating seat 9 that rotates along an annular body 7 provided on the upper wall 1b of the vehicle body 1, and the rotating seat 9 is rotated together with the gun 4 by a link mechanism 10, so that the rotation of the periscope 5 is smooth. Furthermore, the rotational force by the link mechanism 10 does not act on the periscope 5, so that no unreasonable force is applied to the periscope 5 and the periscope 5 is not damaged.

Since the plurality of links constituting the link mechanism 10 are pivotally connected by the ball bush 14, the vertical swinging movement of the gun 4 is absorbed by the ball bush 14 and does not propagate to the rotary seat 9, and the gun 4 is rotated independently of the periscope 5. 4 can be moved up and down.
